I haven't looked at this thing in details. But this data may not be
present forever, say github.com is down or is removed from existence.
So if you can, please always attach any self-contained test case in a
way that it is saved in the archives of postgresql.org. In this case,
that would have been to email directly pgsql-bugs instead of using the
website form.

psql -f initial.sql
# This works
psql -c 'SELECT id, json FROM base_table_json'
psql -f break-it.sql
# this breaks
psql -c 'SELECT id, json FROM base_table_json'
psql -f fix-it.sql
# this works
psql -c 'SELECT id, json FROM base_table_json'

This reminds me of this case:
https://www.postgresql.org/message-id/20150707165212.1188.60819@wrigleys.postgresql.org.
The backtrace is not exactly the same, but that's really close.
